In general anisotropic inhomogeneous elasticity, disturbances propagate along rays which are neither straight nor perpendicular to the wave fronts, but, as in optics, they are still characterized by their rendering the time of travel between two points stationary.

We investigate the spatial behaviour of the steady state and transient elastic processes in an anisotropic elastic body subject to nonzero boundary conditions only on a plane end. For the transient elastic processes, it is shown that at distance x3 > ct from the loaded end, (c is a positive computab
Two principles are basic in the variational formulations of elasticity. Green's "variation for displacements" leads to the principle of minimum potential energy, whereas Castigliano's "variation for stresses" leads to the principle of minimum complementary energy. In the small vibration of elastic b
